Bareilles will make her Broadway acting debut in a 10-week run, from March 31 through June 11. Tony nominee Jessie Mueller, who originated the role, will take her final bow at the Brooks Atkinson Theatre on March 26.

Directed by Diane Paulus, the musical adaptation of the 2007 indie film centers on Jenna, a pregnant, unhappily married diner waitress who hopes her extraordinary pies will allow her a better life. It debuted on Broadway last March and received four Tony nominations, including one for Bareilles' music and lyrics. The cast recording also earned a Grammy nomination for best musical theater album.

Waitress is also the first-ever Broadway musical with an all-female creative team, adding in Jessie Nelson's book and Lorin Latarro's choreography. The production will also kick off its national tour at Cleveland's Playhouse Square this October.

"Waitress has turned out to be one of the great, true loves of my life, and they simply can't get rid of me," she said in a statement. "I consider it an incredible honor to follow the masterful work of Jessie Mueller as she so gracefully brought the character of Jenna to life, and I am thrilled to continue to tell this story that has so much heart. This show changed my life in so many ways, and I feel great privilege in joining our beloved cast and crew who make me laugh and cry every time I watch the show. All I want is to keep sharing the love, and dear God please let me remember my lines."
